Scope: This standard specifies the methods for the determination of inorganic elements in rice wine by inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emis ion spectrometry. This standard applies to lithium (Li), vanadium (V), cobalt (Co), nickel (Ni), gallium (Ga), selenium (Se), strontium (Sr), molybdenum (Mo), and cadmium (Cd) in rice wine , Inductively coupled plasma mass spectrometry determination of barium (Ba) element and sodium (Na), magnesium (Mg), silicon (Si), phosphorus (P), potassium (K), calcium (Ca), manganese (Mn), iron Determination of elements (Fe) and zinc (Zn) by inductively coupled plasma atomic emis ion spectrometry. When the sampling volume is 2.50 mL and the constant volume is 25 mL, the detection limits (μg/L) of this standard method are: Li is 0.04; V is 0.01; Co is 0.04; Ni is 0.08; Ga is 0.08; Se is 0.10; Sr is 0.04; Mo is 0.01; Cd is 0.04; Ba is 0.10; Na is 20; Mg is 20; Si is 60; P is 20; K is 20; Ca is 7; Mn is 2; Fe is 20; Zn is 7.
